The invention relatesto a miter'box and. more particularly to" the classof miter frames for use with hack'saws 'forcutting pipes, bars or thelike. i f

The primary object of the invention is the provision of a frame of thischaracter, wherein the same will receive a pipe or bar,

the latter being held in placeby hand-or by mechanical means, so thatthe pipe or bar can be cut at the proper angle or'cut in two sections,as the hack's'aw is guided'in the frame through a kerf or slotformedtherein,

therebyenablingthe accurate cutting of the pipe or barso as'to*shear-thesame square without bending in the ends and thus avoiding thereducing of'the capacity of the pipe when being cut.

Another object of the invention is the provision of a box orframe ofthis character, wherein the construction thereof is novel in form sothat the same can be readily applied to a pipe, bar or the like to becut, and when thereon will enable the firm gripping of the pipe, bar orthe like and the frame so as to avoid any possibility of relativedisplacement of either the box or frame and the pipe, bar or the like.

Another object of the invention is the provision of a box or frame ofthis character, wherein the bar or the like can be prop- V With theseand other objects in view, the

invention consists in the features of construction, combination andarrangement of parts as will be hereinafter fully described, illustratedin the accompanying drawing and pointed out in the claims hereuntoappended.

Specification of meets Patent. 1. I Patented In' 'the' accompanyingdrawing Figure 1 is a perspective view of the miter box or frameconstructed in accordance with the invention showingfjthe same inposition relative to 'api-p'e to be cut andthe hack saw engaged in thebox or frame "in cutting position. 7 v

Fig. 2 is an enlarged fragmentary side elevation of the pipe showing themiter-box orframethereon'.

Fig. 3? is an end elevation showing-the mi ter box or frame bridging thepipe. Similar reference characters indicate corbeing of the ordinarywell known construction, while the miter box; B will be ihereinafterfully described.

' The miter box comprises a substantially V-shaped frame or "body 5,preferably made from metal, although the same may be made 7 from anyother suitable material and when applied to the work to be cut isinverted as is clearly shown in Figs. 1, 2 and. 3 of the drawing. Theframe or body 5 includes side portions 6 which are for a major portionof their length cutaway to provide finger recesses 7 for accommodatingthe fingers and the thumb of the hand of the user when the frame or body5 is applied to the pipeA, bar or other piece of work to be out by thehack saw 0 in the manner as shown in Fig. 1 of the drawing.

The frame or, body 5 on oppositesides of the recesses 7 constituteguides 8 and 9 respectively, the guide 8 beingof considerably greatersize than the guide 9 and in this said guide 8 transversely of the frameor body 5 is a kerf or slot 10 of a size to accommodate the blade of thesaw C, as shown inserted in the kerf or slot 10 of the miter box orframe in Fig. 1 of the drawing, to permit recipro- V cation of the bladeof the saw in the 'opera- 7 tion thereof for the severing of the pipe A,

bar or other like piece of work.

It is of course to be understood thatthe kerf or slot 10 can be disposedin true transverse position through. the body 5 of the miter box orframe yet the said kerf or slot can be disposed at any desired angleaccording to. the nature of the cut to be made in the bar or the like inthe use of the miter box for the severing of said pipe, bar or the like,either at an angle or stra ght across the same as the occasionmayrequire.

The miter box in the constructionthereof is especially adaptable incutting pipes, iron" or otherlike pieces of work and the same is appliedthereto in the manner as shown in Figs. 1, 2 and 3 of the drawing, sothat the hand of the operator of the saw can grip the miterabox throughthe. looprecesses 7 and also the-piece of workdisposed Within the box,thelatter being inbridging relation ito thework, thus itbeingseen thatthe work and the miter box will be firmly held against displacement ;sothat theuhacksaw when operated in the kerf or slot 10 will be guided forthe severing of the work. If found .ex-

pedient the miter box in the construction as hereinbefore set forth canclamp a piece of work in any desirable manner otherthan the handclamping thereof as isillustrated in Fig. 1 of the drawing.

It is of courseto be understood that changes, variations andjmodificatiotns may be made in this invention, such as come properlywithin the ,scope of the appended,

cla1ms, without departingfrom the spirit of the invention or sacrificingany of: itsadvantages. a 4 U a 1 It is thought that the construction andmanner of use of the miter box will be clearly understood and therefore,a more extended explanation has been omitted.

What is claimed is 5 A miter box of the character described, comprisinga substantially 'V-shaped frame adapted to be inverted for bridging apiece adapted, to be inverted forbridging a piece of work and having akerftherein for guiding a hack saw operated forsevering the piece ofwork, the frame being provided with finger recesses in the sides thereofto effect a hand grip on the frame and piece of work when the saidframeqis in inverted bridging relation to the work.

V 3. A miter box comprising a body, having a V-shaped space forreceiving a piece of work, said frame being formed with a kerf verselyto the longitudinal extent thereof, said frame being: further formedwith re cesses to accommodatethe'fingers and thumb of the hand of a userfor the gripping of saidtfr ameiand a pieceof Work when posed within theV-sha ed s ace.
